Signed distance functions, or SDFs for short, when passed the coordinates of a point in space, return the shortest distance between that point and some surface. The sign of the return value indicates whether the point is inside that surface or outside (hence signed distance function). Let’s look at an example. fix my background color

WebIn hierarchical ray tracing, on "the way down" you should transform the point and vector forming the ray with a node's inverse transform. On "the way back up" you should transform the intersection point by the original transformation, and (assuming you represent the normal as a column vector) you should transform the normal with the transpose of the upper-3×3 …
